By popular request - we now have a way you can turn on-and-off Lithium Polymer batteries without unplugging them.
This PH2 Female/Male JST 2-pin Extension Cable comes with an in-line Switch - click once to turn on, click again to turn off. It's super handy especially in tandem with our JST-terminated battery packs or LiIon & LiPoly batteries/accessories/chargers!
One end has a classic female JST-PH2 socket, and the other end has a matching plug. From end to end the cable measures ~20" / ~508mm.
